Dropbox download via API unstable under Pyodide (xlwings lite)

Ruud van der Ham

I am using the Python dropbox module to download files in pyodide (actually xlwings lite).

I see that quite often a file is not downloaded completely, without even raising an error.

Is there a workaround or patch or ... ?

Uploading files seems to work as expected.

This is most likely due to incomplete streaming support in pyodide. You should try downloading in chunks and checking the file size or checksum after the transfer. As the Dropbox SDK itself will not throw an error if the streaming ends prematurely.

I have managed to read reliably from Dropbox by avoiding the dropbox module and using requests directly.

Under xlwings lite it is all a bit more tricky as you have to do

pyodide.http.patch_all()

as well.

This now implemented in xlwings_utils (www.salabim.org/xlwings_utils).
